The Lab Companion AAA3A531 rubber mat is non-skid and fits a 320 - 260mm/12.6 - 10.2-inch (W x D) platform on an SKF-2000 series economy shaker. (W is width, the horizontal distance from left to right; D is depth, the horizontal distance from front to back.) The mat is designed for low-speed applications and allows for quick addition or removal of flat-bottomed labware. The mat is an accessory for the SKF-2025, SKF-2050, SKF-2075, SKF-2025R, SKF-2050R, and SKF-2075R shakers.

Laboratory shakers agitate liquids during laboratory procedures. These devices can be analog or digital and are typically an automated, electrically powered, countertop unit that shakes liquid in lab containers, such as flasks, funnels, or test tubes. Some shakers can operate inside fume hoods, incubators, refrigerators, or other laboratory devices, and can include controls for the frequency and/or degree of movement. The types of shakers include: orbital, rocking, rolling, rotating, and wrist action. The most common orbital shaker provides a smooth, continuous, circular motion, sometimes with a tilt angle, for uniform mixing of contents. The rocking shaker creates gentle uniform mixing with a see-saw, or up and down, motion. Reciprocating, or rolling, shakers provide a horizontal side-to-side motion with simple agitation of samples. A rotating, or rotisserie, shaker provides samples with a rotating action that moves in a circular motion. Wrist-action shakers duplicate the effect of hand mixing with "arms" on each side of the unit. Some shakers have the ability to incubate or refrigerate samples while providing shaking action.
